You need to paint a view before you can show a button. You could create
a QMainWindow and add the QPushButton in there I suppose, but I'd
strongly recommend to not use QWidget, but instead QML.

As a quick start start:

main.cpp:

#include <QQuickView>
#include <QCoreApplication>

int main(int argc, char *argv[]) {
  QGuiApplication app(argc, argv);
  QQuickView v;
  v.setSource("/path/to/some/qmlfile.qml");
  v.show();
  return app.exec();
}

/path/to/some/qmlfile.qml:

import QtQuick 2.4
import Ubuntu.Components 1.3

MainView {
  Button {
    anchors.centerIn: parent
    text: "click me"
    onClicked: print("button clicked")
  }
}
